Not Ranked
Assuming no PSV then flowrate will be the same cold, hot, low viscosity, high viscostiy. Pressure drop does not matter to a positive displacement pump until it reaches the material limits of what the pump is constructed from or driven by. I am not getting into volumetric vs mass flow and temperature correlations so all you fluid dynamic experts can go into the details.
I was quoting another post and the lower one was my reply. I suk at highlighting, I apologize for the confusion.
